Alisa Haiba

Alisa is an older sister of first year Nekoma Team player: Lev Haiba. From the moment of her debut, Alisa has acted as lively and bubbly, but also as innocent as her brother is. She is very supportive of Lev, affectionately referring to him as "Lyovochka" and cheering him on during his match. It's also been implied that she's a bit of an imaginative romantic, which was shown when she quickly jumped to the conclusion that Akane was in love with Lev. (Source: Haikyuu!! Wikia)
